The new ECL202
eddy-current displacement/position sensor has significantly improved
thermal stability and immunity to electromagnetic interference
(EMI) as well as improved linearity and resolution.
The sensor employs FPGA technology enabling complex, proprietary
mathematical algorithms to achieve higher performance levels
than purely analog methods. According to Don Martin, president
of Lion Precision, Using FPGA digital processing techniques,
we can achieve performance that simply is not possible with discrete
analog electronics.

Digital technology
can very precisely detect the sensors signal and more easily
differentiate it from other electrical signals present in the
sensing environment. This means the sensor continues to work
well in electrically noisy environments such as near motor controllers
or other high-power switching electronics. Using this same proprietary
method, multiple ECL202 sensors can be positioned near each other
without the mutual interference usually experienced with eddy-current
sensors.

Internal calibration
tables of tens of thousands of points assure precise linearity.
Achieving these same levels of linearity with analog circuitry
often involves a trade-off between linearity and other performance
parameters such as thermal stability or resolution. With digital
technology, this trade-off is no longer required. The ECL202
sensor is maximized for all of these parameters. Digital circuitry
is immune to drift associated with analog circuitry, providing
the ECL202 with greater thermal stability than analog designs.

The ECL202 also
offers new features only available with digital technology: push-button
offset adjustment, push-button setpoint adjustment, external
offset and setpoint adjustments and user-selectable bandwidths.
